It involves a bunch of teenagers at a secluded boarding school who, after hearing rumors about a local murder, decide to play a mass prank of sorts, using common SlasherFilm tropes to invent a serial killer and spread fear throughout the campus. It turns out the joke's on them, as they begin to receive threatening messages from someone claiming to be the serial killer they invented.

The film contains a top-drawer performance from Creator/LindyBooth as a [[FilleFatale sexpot schoolgirl]]. The movie also features Julian Morris, [[Music/BonJovi Jon Bon Jovi]], Gary Cole and Creator/JaredPadalecki.

''For the trope, see CryingWolf.''----!!Contains examples of:

* AnimalMotifs: Wolves and sheep of course. The serial killer is named 'The Wolf', the lying game separates people into 'sheep' and 'wolves', the weapon of choice is a hunting knife, Dodger dresses up as Little Red Riding Hood for Halloween and her screen name has 'Bo Peep' in it.* ArcWords: "They're the sheep. And we're the wolves."* TheBadGuyWins: [[spoiler: Dodger gets everything she wants, exactly as she planned it.]]* BatmanGambit: ** Owen pulls this on Mr. Walker, and the patsies are the administration.** [[spoiler: Dodger's whole plan is a giant BatmanGambit. So giant that it's actually a GambitRoulette.]]* BoardingSchool* BrickJoke: The scene where the group discusses previous "victims" includes a comment about the murderer hiding in the back seat of a car, which is instantly dismissed as cliché. [[spoiler:When Owen starts up Tom's car, Mercedes is in the back seat. Bonus points for Owen's attempt to subvert [[AlwaysMale another trope]] in character while doing so.]]* CatholicSchoolGirlsRule: OK, technically it's not a Roman Catholic school, but Dodger walks squarely into this trope.* ChekhovsGunman: A couple of times we see the school janitor glaring at Owen. It turns out [[spoiler: he's Dodger's father. Though he has no role in the plot]].* ChekhovsHobby:** [[spoiler: It's mentioned that Regina has a flair for making fake blood]].** [[spoiler: Lewis is described as an aspiring actor]]. * TheChessmaster: Owen makes a hobby of it. [[spoiler:He's an amateur compared to Dodger.]]* CryingWolf: The film carries the tagline "You lie, you die."* DangerTakesABackSeat: Suggested by Mercedes when creating the killer. She's shot down for it being too cliche. [[spoiler: She exploits this later when pranking Owen]].* DeathByGenreSavvy: In a way. [[spoiler: One of the characters uses the other characters' knowledge of HorrorTropes to cause another character to kill a man she wants revenge on, making this [[MindScrew murder by genre savvy by proxy.]]]]%%* DeceasedFallGuyGambit* [[spoiler: EvilRedhead: Dodger]]* FalseRapeAccusation: [[LampshadeHanging Lampshaded]] by Owen - if Mr. Walker gets accused of it, he ''will'' be fired, no matter if there's any evidence at all or not.* FakingTheDead: Dodger pretends to drown in the pool to mess with Owen and Tom. * FilleFatale: Dodger who is in a relationship with her teacher. What's more is that it's implied that ''she'' seduced him. * FiveTokenBand: We have a Brit (Owen), a white girl (Dodger), a black guy (Lewis), an Asian girl (Regina), a Latina girl (Mercedes) and two more white dudes in Tom and Randall.* ForeShadowing: [[spoiler: During the "Wolf creation" scene Randhall basically tells almost everything we need to know about Owen's fate in the film.]] * HeroesWantRedheads: This is the case with Owen and Dodger.* {{Homage}}: The scene where [[spoiler:Dodger pretends to drown in the pool]] is a clear homage to ''Film/FridayThe13th1980''.* HorrorDoesntSettleForSimpleTuesday: Knowingly invoked, as the fictional 'Wolf' is supposed to strike on Halloween night. * HotForStudent: Dodger and Mr. Walker.* GambitRoulette: [[spoiler: Dodger's]] plan would have fallen apart instantly had any number of perfectly likely things happened.* INeedToGoIronMyDog* KarmaHoudini: [[spoiler:Dodger arranges this all so that she can be this for her part in Becky's murder]].* MeaningfulName: Dodger. [[spoiler: As in she ''dodges'' [[KarmaHoudini karma]]]].* NeverTrustATrailer: Contrary to what the marketing would have us believe, ''Cry_Wolf'' is not a slasher movie (though it does intentionally employ many tropes of the genre), and its lack of graphic violence is [[JustifiedTrope justified]]. Most of the footage in the trailer is not in the movie at all and is in fact contradictory to the movie.* ProductPlacement: AOL, Chrysler and [[EveryoneOwnsAMac Apple]]. Justified, in the case of Chrysler, as the film was financed as part of contest. The story can be found on the DVD extras.* SexyWhateverOutfit: Dodger has a sexy Red Riding Hood costume for Halloween.* ShoutOut: Dodger's ICQ nick is revealed to be BoPeep05 - an obvious reference to [[IronicNurseryRhyme nursery rhyme]] Little Bo Peep who "has lost her sheep". Which alludes to the "Wolf and Sheep" game they played. [[spoiler: Or to her being AWolfInSheepsClothing.]]* SlashersPreferBlondes: The movie opens with a blonde getting murdered.* {{Tagline}}: "You lie. You die."* TeensAreMonsters: Since their idea of fun is to spread a rumour that a serial killer could be on the loose, only a couple of weeks after a local girl is murdered. The story gets emailed to the girl's ''mother''. Additionally at the Halloween dance, a few people are dressed up as the Wolf in question.* TheyReallyDoLoveEachOther: Owen's father spends most of the movie putting his son on voicemail and dodging his calls. [[spoiler: After Owen kills Mr Walker]] the father flies all the way to the police station, hugs his son sincerely and comforts him.* TokenMinorityCouple: The BetaCouple to the white Owen and Dodger are black Lewis and Latina Mercedes.* TooDumbToLive: Seriously, [[spoiler: Mr.Walker. Trying to attack an extremely unsettled gun-armed kid certainly wasn't the wisest decision. Even more so given that Owen was seemingly very reluctant to shoot, and a calm conversation could have helped.]] * TwistEnding: Combined with a repeated GenreShift.[[spoiler: Half an hour before the ending, the film is a somewhat melodramatic thriller. Twenty minutes before the movie ends, it's your typical teen slasher movie. Ten minutes, it's Film/AprilFoolsDay GoneHorriblyRight. At the very end, it turns out to be a film noir.]] * UnreliableVoiceover* UnwittingPawn: [[spoiler:Owen.]]* WhatTheHellHero: Happens quite often to Owen, who is both genuinely likable and highly amoral. He could be a MagnificentBastard, but, as Dodger tells him, he's "too nice."* WithFriendsLikeThese: All over the place. Despite being a group of friends, they seem to play tricks on each other ''often''. This is lampshaded by Dodger after they plan their story, saying this is only possible after being together four years.* WrongGenreSavvy: It's only at the very end that it becomes clear [[spoiler: this isn't a slasher film. It's a film noir.]]* {{Yandere}}: [[spoiler:Dodger is this for Mr Walker.]]
